Product Overview
This rabbit polyclonal antibody detects C-X-C motif chemokine 13 (gene CXCL13) in human samples and is validated for Western blot. The predicted molecular weight is 12.7 kDa, and the supplier reports an observed band at about 13 kDa.
CXCL13 (BLC) is a chemokine that attracts B cells through the receptor CXCR5. Produced by stromal cells in lymphoid follicles, it organizes B-cell follicles and guides follicular helper T cells. CXCL13 is also studied in ectopic lymphoid structures that form in chronic inflammation, autoimmunity and some tumors.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|
Samples with a confirmed band (WB): HeLa cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Immunogen
Recombinant human BCA1 fragment (Val23–Pro109), expressed in E. coli. Sequence identity with the mouse ortholog: 45.3%.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes C-X-C motif chemokine 13 as a secreted protein. Tissue expression noted by UniProt (human): Highest levels in liver, followed by spleen, lymph node, appendix and stomach. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
